GAS-STOVE.

SPECIFIGATION'formingpart of Letters Patent No. 745,711, dated December -1, 1903.

Application filed June 19, 1903, Serial No. 162,214. (No od l.) I v To all whom, it may concern.-

Be it known that we,'JULIUs F. ADAMS and Fnrnnnnrcn O. ADAMS, citizens of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention'relates to gas-stoves, and has particular reference to the type of stove shown in patent to Adams and Donaldson, December 3, 1901, No. 688,051.

One object is to improve the arrangement or position of the burner. V

Another object is to provide a product drum or chamber .of novel design.

Still a further object is to simplify and improve the general constructionof the stove, particularly its upper, lower, and back portions.

In the accompanying drawings, Figure 1 is a front elevation ofa stove embodying our improvements, a portion of thetop or crown being broken away. Fig. 2 is a top plan view, partly in section. tudinal sectional view on line 3 3 of Fig. 4:. Fig. 4 is a vertical cross-sectionalview on line 4 4 of .Fig. 3. Fig. 5 is a sectional plan view on line 5 5 of Fig. 1. Fig. 6 is a rear elevation of the upper portion of the stove. Fig. 7is a detail view of the upper back plate. Fig. 8 is a similar view of the drum-forming structure. Fig. 9 is a detail view of the burner.

The invention is here embodied in a stove,

of semicircular design; and it consists of a curved sheet-metal base 2, having the l11-' weirdly-flaring top portion 3, which terminates in the curved horizontal flange 4. In the front of the base is open-work panel 2',

and at the rear the base ends unite at 5 with 9 designates the curved tubular burner po-- sitioned adjacent the fire-board and slightly Fig. 3 is a vertical longi-.

neath the burner to afford a direct upward" supply of air thereto. The burner is secured by being brazed to the mixer-stem 10, which extends through flange o and which unites with supply-pipe 11, the latter being sustained by hanger l2 and the stove-back. With the burner-slightly above the perforated base it is afforded a direct upward supply of air.

'9' is a deflecting-plate brazed to the interior of the burner and positioned centrally over the stem 10, said plate afiording an even distribution of gas throughout the burner. The deflector is curved in conformity with the burner and is inserted through the burnerbottom opening, to which stem connects.

V Raised slightly above the upper end of fireboard 8 is the curved cast-metal plate 13, having depending lugs 13, Y to which the fireboard is secured, and projecting forward and down ward from this plate over the upper end of the fire board is the curved and inclined deflector 14, which directs the products through .openingl5, formed by plate .13 and the top'extremity of the fire-board.

A product-receiving chamber is formed within the stove by two horizontal partitionplates 16 and 17, rigidlyconnected by vertical tubes 18; Lower plate 16 exactly fits the space between the stove-back and fire-board,

While plate 17 rests on and is secured to curved cast plate 13, so that said partitionplates, in conjunction with the vertical mem-' bers of the stove-frame, form a chamber of which passage constitutes the entrance for the products passing from the fire-board.

Back plate 6 terminates between partitions l6 and 17 and is formed at'its upper'edge with the bent-up groove 19, in which is supported the vertical cast-metal plate 20, having flue connection 21. V Said plate completes the rear wall of the drum and extends there above: and at its top edge is shaped to form the top outline of the stove and at said edge has lateral lugs to which is secured the edge of the ornamental top or crown 22,formed preferably of sheet-brass. The top is of semidome form and has an annular flat surface immediately over cast plate 13, to which it is secured by screws 23, the arrangement being such that said screws also serve to secure deflector 14. The lower portion of the ornamental top forms a skirt 22", which extends over and obscures deflector 14.

The forwardly-curved fire-board terminates between the ornamental columns 24; at either side of the stove, said columns being formed, preferably, of sheet-brass and are secured to the edges of back plate 6 by vertical seams 25.

The stove-top is perforated at 26, and with the base open, as shown, there is ample provision for air to circulate through the stove and become heated, especially as it courses through tubes 18 of the product-chamber.

A stove of the form here shown and described is very substantial and durable and at the same time comparatively inexpensive, the parts being of simple construction and of the smallest possible number. The base and fire-board, being of sheet metal, are liable to become distorted under constant wear and intense heat when unprovided with stiffening means, which in the present structure is provided in the form of plate 7, which serves to permanently unite said parts and preserve their form. In like manner the upper portion of the stove, including the top of the fireboard, is reinforced by plate 13. The cast back plate 20 provides a convenient flue connection without seaming, and its top edge may be cast to conform to the shape of the top which fits thereover-a formation that would be difficult and more costly in sheet metal,

It will be understood that many features of our invention may be embodied in stoves differing in shape from that here shown without departing from the spirit thereof.

We claim- 1. In a gas-stove, an upright semicircular sheet-metal fire-board, a back plate to which the vertical edges of the fire-board are secured, and curved horizontal plates defining the shape of the fire-board and to which the same is secured.

2. In a gas-stove, an upright frame including a fire-board and a back, horizontal plate 13 to which the upper end of the fire-board is secured, horizontal partition-plate 17 secured to plate 13, tubes 18 depending from plate 17, plate 16 at the lower ends of the tubes and fitting the interior of the frame, the space between plates 16 and 17 being open for the admission and discharge of products.

3. In a gas-stove, a frame including an upright fire-board, horizontal plate 13 to which the upper end of the fire-board is secured, defleetor 14 and top 22 secured to said plate, the top having skirt 22 overhanging deflector 14.

4:. In a gas-stove, an upright frame including a fire-board, horizontal plate 13 to which the upper end of the fire-board is secured, deflector 14 and top 22 secured to said plate,
